IAPI

Import items from external programs/generators.

For Players: Click the IAPI import option in whatever program you're using. Make sure you are in creative.

For Developers: Send a POST request to the local device (127.0.0.1), with a port. The default port is 25530.

// Web Javascript Example

port = 25530; // It is recommended that you provide an option to change this.

// Most webbrowsers do not allow getting data back from this request.
// Game logs will indicate what went wrong.
// If you are using a desktop application, this is not a problem.
fetch("http://127.0.0.1:" + port, {
  method : "POST",
  headers : {
    "Content-Type" : "text/plain"
  },
  body : "minecraft:stone{display:{Name:'\\'Happy Stone\\''},Enchantments:[{}]}"
});
